The object'of our invention isto provide` Still a further object is toprovide arms on our repair stake which extendalong the sides of thebolster and beneath'the wagon bed for securely fastening the repairstake to the bolster.

Still a further object is to provide a means on our repair stake toengage the en d of the bolster which further braces the stake to preventthe upper end from being forced outwardly.

Still a further object is to provide a repair stake which can be appliedto a bolster from which the original stake has been broken) with the aidof a saw, a wrench and a brace and bit.

Still a further object is to provide eXtension stake loops on ourrepair' stake, the fastening means of which serve to hold the parts ofthe stake in assembled position.

With these and other objects in View, our inventionv consists in theconstruction, arrangement and combination of the various parts of ourbolster repair stake, whereby the objects contemplated are attained, ashereinafter more fully set forth, pointed out'in our claims, andillustrated in the accompanying drawings, in which:

Figure 1 is a perspective View of our improved repair stake.

Figure 2 isa side elevation of the same illustrating it applied to abolster from which the original stake has been broken; and

Figure 3 is a detail sectional view taken on the line 3 3 of Figurev 2.

On the accompanying drawing I have used the reference numeral 10 toindicate generally the bolster of a wagon. The bolster 10 may be eitherthe front or rear bolster inasmuch as our repair stake can be applied toeither with equal eiificiency. Ordinarily the bolster 10 is longer thanillustrated as indicated by the end 12 which is shown by dot and dashedlines. The original stake as constructed onY the general type of wagonsnow in use has a tenon formed on its lower end designed to fit in amortise cutinthe bolster 10. At the most, such a stake is rather amake-shift device and very frequently breaks rMen-*r ePrice-.

offr in the mortisemand tenon joints. If .in

breal'ring off itsplits the end12 of the bolster, it is almostimpossible to attach 'another stake. to the end of the bolster.y Toovercomev this objection, we yhave provided our repair .stake with meansfor securing it to the side of t-he bolster under the wagon bed.

Our improved repair stake comprises a pair o f side members 14 formed ofcast steel or malleable iron or the like. Side members 14 haveinwardlyprojecting arms 16 adapted to it along the sides fof thebolster- 10. The arms 16 are provided with openings n 18. pair ofextension stakeloops 20 are provided pivoted to the side members 14 byrivets or the like22.

A filler block 24 is positioned between the i side members 14 and heldin position by the rivets 22. It will be noted that the end 26 of thefiller block 24 extends below the arms 16.

When the original stake of the bolster 10 is broken `off, the bolster issawed'oft' on the line A28 at the outermost extremity of the wagon 16.Bolts82 are then positioned throughk the openings 18 and 30 and the nuts4 are applied to them for securely clampingthe y arms 16 to the sides ofthe bolster 10. n'

The arms 16 help in a great measure to prevent the upper ends of thestake from being bent outwardly. However the end 26 of the filler block24 serves a substantial pur- .n

pose for further bracing the repair stake.

It will be noted that an outward tendency7 against the upper end of thestake forces the end 26 against the end of the bolster for servi ing asa rigid brace. Y

The side members 14 are additionally reinforced by the thickenedportions 36 cast along the side members and the arms 16.

From the foregoing description it will be obvious that we have provideda repair stake which is very eiicient and which can be easily andquickly used to replace the orignal stake when broken olf.

Some changes may be made in the arrangethe real spirit and purpose ofour invention,

and it is our intention to cover by our claims,

the `Wagon .and the vertical arm including,

means for securing said horizontal portion including a pair of arms andan insert se-` cured therebetween, said insert to the sides of abolster, said upright portion extending below thehorizontal portion ofthe stake and adapted to restV against the end of the bolster."
